[0029] Referring to Figure 1 As shown, this embodiment discloses a lifting tool for the construction of long-distance natural gas pipelines, which includes a gantry hanger body 1, a positioning device 4 and a fixing device 5 installed between two columns 6. The columns 6 are vertically fixed on the ground. A moving plate 2 is slidably connected to the surface of the gantry hanger body 1. A motor body 3 is arranged on one side surface of the moving plate 2. The positioning device 4 is installed on the surface of the moving plate 2 by means of the fixing device 5. Among them, a hook 7 is installed at the bottom of the moving plate 2 through a winch.

[0030] Referring to Figure 1 and Figure 2 as well as Figure 3 As shown, this embodiment discloses that the positioning device 4 includes a mounting plate 41. The mounting plate 41 is installed on one side surface of the moving plate 2 by means of the fixing device 5. A servo motor 42 is fixedly connected to the surface of the mounting plate 41. The output end of the servo motor 42 is fixedly connected to a gear 43. A mounting rod 44 is fixedly connected to one side surface of the gantry hanger body 1. A number of uniformly distributed fixing grooves 45 are formed on the surface of the mounting rod 44. A limiting plate 47 is fixedly connected to one side surface of the mounting plate 41. A toothed plate 46 is slidably connected to one side surface of the limiting plate 47. A limiting groove 48 is formed on the surface of the toothed plate 46. The limiting plate 47 is slidably connected to the inner wall of the limiting groove 48. The gear 43 meshes with the toothed plate 46. The toothed plate 46 is slidably inserted into the inner wall of the fixing groove 45. When the gantry hanger body 1 is in use and drives the manipulator to carry out processing and production, first start the motor body 3 on the gantry hanger body 1 to make the moving plate 2 slide on the gantry hanger body 1 to the position where the natural gas pipeline is transferred. Then start the servo motor 42 on the mounting plate 41. Because the gear 43 on the servo motor 42 meshes with the toothed plate 46, and the sliding of the limiting plate 47 and the limiting groove 48 limits the toothed plate 46, the toothed plate 46 approaches the mounting rod 44 under the drive of the servo motor 42 until the toothed plate 46 is inserted into the inner wall of the fixing groove 45 of the mounting rod 44. At this time, during the use of the gantry hanger body 1, it can well ensure the lifting of the natural gas pipeline, and it is not easy to shake and shift in position, improving the processing accuracy and work efficiency, and further improving the use effect and practicability of the gantry hanger body 1.

[0031] Referring to Figure 1 and Figure 2 as well as Figure 3As shown, in this embodiment, reinforcing rings 411 are fixedly connected to the inner walls of a number of fixing grooves 45 respectively. The reinforcing rings 411 are rubber rings. Through the arrangement of the reinforcing rings 411, when one end of the toothed plate 46 is inserted into the fixing groove 45, the frictional force is further increased and gaps are not easily generated, thus better ensuring the stable position of the moving plate 2 and improving the displacement accuracy when the gantry crane body 1 drives the robotic arm. A protective plate 410 is fixedly connected to the surface of the mounting plate 41. The protective plate 410 covers the surface of the gear 43. Through the arrangement of the protective plate 410, during the normal production and processing of the gantry crane body 1 when the positioning device 4 is in use, metal debris and the like are not easily adhered to the gear 43, thereby ensuring the normal use of the positioning device 4.

[0032] Referring to Figure 1 and Figure 4 As shown, in this embodiment, a stabilizing hole 49 is formed in the surface of the limiting plate 47. The output end of the servo motor 42 is rotatably connected to the inner wall of the limiting hole. Through the arrangement of the stabilizing hole 49, when the servo motor 42 drives the gear 43 to rotate, the rotation of the gear 43 is more stable, and the toothed plate 46 can be driven more stably. A strip-shaped groove 412 is formed in one side surface of the mounting rod 44 of the positioning device 4. The mounting plate 41 is slidably connected to the inner wall of the strip-shaped groove 412. Through the arrangement of the strip-shaped groove 412, when the mounting plate 41 moves along with the moving plate 2, the mounting plate 41 can better maintain its position stability, and thus better accurately position the moving plate 2 used by the gantry crane body 1.

[0033] Referring to Figure 1 and Figure 4 As shown, in this embodiment, the fixing device 5 includes a mounting frame 51. The mounting frame 51 is fixedly connected to the surface of the moving plate 2. The mounting plate 41 is inserted into the inner wall of the mounting frame 51. A threaded hole 52 is formed in one side surface of the mounting frame 51. A bolt 53 is threadedly connected to the inner wall of the threaded hole 52. The bolt 53 is threadedly connected to the surface of the mounting plate 41. When assembling the positioning device 4, first insert the mounting plate 41 into the inner wall of the mounting frame 51 on one side surface of the moving plate 2, then thread the bolt 53 into the inner wall of the threaded hole 52 on the surface of the mounting frame 51, and then thread the bolt 53 onto the surface of the mounting plate 41. At this time, when the positioning device 4 is in use, it can be more convenient, and it is also convenient to repair and maintain the positioning device 4, ensuring its normal use.

[0034] In this embodiment, an operation block 54 is fixedly connected to the surface of the bolt 53, and a number of anti-slip protrusions are provided on the surface of the operation block 54. Through the setting of the operation block 54, the bolt 53 is more convenient to use during operation, and then the bolt 53 can be quickly threadedly connected to the mounting plate 41, improving the convenience of use of the fixing device 5. On both sides of the surface of the mounting frame 51, clamping grooves 56 are respectively formed. A clamping block 55 is clamped to the inner wall of the clamping groove 56, and the clamping block 55 is fixedly connected to one side surface of the mounting plate 41. Through the clamping setting of the clamping block 55 and the clamping groove 56, the assembly stability of the mounting plate 41 and the mounting frame 51 is further improved, and then the assembly stability of the mounting plate 41 is more stable, improving the use effect of the fixing device 5.

[0035] Working principle: When the gantry crane body 1 is in use, first bind the natural gas pipeline to be lifted with a steel cable, and then hook the hook 7 on the steel cable. The winch winds up the hook 7 to lift the natural gas pipeline. Start the motor body 3 on the gantry crane body 1 to make the moving plate 2 slide on the gantry crane body 1 to the position where the natural gas pipeline is transferred. Start the servo motor 42 on the mounting plate 41. Because the gear 43 on the servo motor 42 meshes with the toothed plate 46, and the sliding of the limiting plate 47 in the limiting groove 48 limits the toothed plate 46, the toothed plate 46 approaches the mounting rod 44 driven by the servo motor 42 until the toothed plate 46 is inserted into the inner wall of the fixing groove 45 of the mounting rod 44. At this time, during the use of the gantry crane body 1, the lifting of the natural gas pipeline can be well guaranteed, and it is not easy to shake and shift in position, improving the processing accuracy and work efficiency, and further improving the use effect and practicability of the gantry crane body 1.

[0036] When assembling the positioning device 4, first insert the mounting plate 41 into the inner wall of the mounting frame 51 on one side surface of the moving plate 2, and make the clamping block 55 on the mounting plate 41 be clamped in the clamping groove 56 on the surface of the mounting frame 51. Then rotate the operation block 54 on the bolt 53 to threadedly connect the bolt 53 to the inner wall of the screw hole 52 on the surface of the mounting frame 51, and then threadedly connect the bolt 53 to the surface of the mounting plate 41. At this time, when the positioning device 4 is in use, it can be more convenient, and it is also convenient to repair and maintain the positioning device 4, ensuring normal use.
